Canada 1987 dollar KM-157

In 1987, Canada retired her "voyageur" dollar, which did not circulate, and her paper dollar, which deteriorated quickly, for this brass plated nickel coin, quickly dubbed the "loonie." Enormous quantities were minted 1987-89 using this bust before being supersede by KM 186, which featured the de Pedery-Hunt bust of the queen. Later mintages, however, were much more modest, a warning not heeded during the later introduction of the Sacagawea dollar in the United States.
